Hast thou killed, and also taken possession? - These words rebuke especially Ahab’s indecent haste. He went to Jezreel the very day after Naboth’s execution 2 Kings 9:26.
The prophecy following had a double fulfillment. The main fulfillment was by the casting of the dead body of Jehoram into Naboth’s plot of ground at Jezreel, where, like Naboth’s, it was left for the dogs to eat 2 Kings 9:25. This spot, which was just outside the city wall, and close to a gate 2 Kings 9:31, was probably the actual scene of Naboth’s execution. Here did dogs lick Ahab’s blood, that is, his son’s blood, the execution of the full retaliatory sentence having been deferred to the days of his son, formally and explicitly, on Ahab’s repentance 1 Kings 21:29. But, besides this, there was a secondary fulfillment of the prophecy, when, not at Jezreel but at Samaria (marginal reference), the actual blood of Ahab himself, was licked by dogs, only in a way that implied no disgrace. These two fulfillments are complementary to each other.
